At 10:30 the six guns of the 26th Jacobs Mountain Battery arrived, positioning three guns each side of White's Valley. At noon they opened fire on the Turks on Gun Ridge.
Within two hours half the Australian Division was involved in the battle of 400 Plateau. However, most of the officers had misunderstood their orders. Believing the intention was to occupy Gun Ridge and not hold their present position, they still tried to advance. The 9th and 10th Battalions had started forming a defence line, but there was a gap between them that the 7th Battalion was sent to fill. Seeing the 2nd Brigade coming forward, units of the 3rd Brigade started to advance to Gun Ridge. The advancing Australians did not then know that the counter-attacking Turkish forces had reached the Scrubby Knoll area around 08:00 and were prepared for them. As the Australians reached the Lone Pine section of the plateau, Turkish machine-guns and rifles opened fire, decimating the Australians. To the north other troops, advancing beyond Johnstone's Jolly and Owen's Gully, were caught by the same small arms fire. Soon afterwards a Turkish artillery battery also started firing at them. This was followed by a Turkish counter-attack from Gun Ridge. Such was the situation they now found themselves in that at 15:30 McCay, now giving up all pretence of advancing to Gun Ridge, ordered his brigade to dig in from Owen's Gully to Bolton's Ridge. Pine Ridge is part of the 400 Plateau, and stretches, in a curve towards the sea, for around one mile (1.6 km). Beyond Pine Ridge is Legge Valley and Gun Ridge and, like the rest of the terrain, it was covered in a thick gorse scrub, but also had stunted pine trees around eleven feet (3.4 m) tall growing on it. Several groups of men eventually made their way to Pine Ridge. Among the first was Lieutenant Eric Plant's platoon from the 9th Battalion. Captain John Whitham's company of the 12th Battalion moved forward from Bolton's Ridge when they saw the 6th Battalion moving up behind them. As the 6th Battalion reached the ridge, the companies carried on towards Gun Ridge, while Lieutenant-Colonel Walter McNicoll established the battalion headquarters below Bolton's Ridge. As the 6th Battalion moved forward they were engaged by Turkish small arms and artillery fire, causing heavy casualties. At 10:00 brigade headquarters received a message from the 6th Battalion asking for reinforcement, and McCay sent half the 5th Battalion to assist. At the same time the 8th Battalion were digging in on Bolton's, except for two companies which moved forward to attack a group of Turks that had come up from the south behind the 6th Battalion. By noon the 8th Battalion was dug in on the ridge; in front of them were scattered remnants of the 5th, 6th, 7th, and 9th Battalions, mostly out of view of each other in the scrub.
